# Licensed



Licensed caches the licenses of dependencies and checks their status, and is available as a Ruby gem.



Licensed is **not** a complete open source license compliance solution. Please understand the important [disclaimer](#disclaimer) below to make appropriate use of Licensed.



## Current Status



![Build status](https://github.com/github/licensed/workflows/Test/badge.svg)



Licensed is currently in **low maintenance mode**. At this point, we're only looking to maintain this repository for security fixes.



## Licensed v4 - **Removed support for non-Ruby environments**



Licensed v4 no longer provides a self-contained executable build of licensed.  Please see [the deprecation notice](https://github.com/github/licensed/issues/585) for more context.



## Licensed v3



Licensed v3 includes a breaking change if both of the following are true:



1. a project uses bundler to manage ruby dependencies

2. a project uses the self-contained executable build of licensed



All other usages of licensed should not encounter any major changes migrating from the latest 2.x build to 3.0.  



See [CHANGELOG.md](./CHANGELOG.md) for more details on what's changed.

See the [v3 migration documentation](./docs/migrations/v3.md) for more info on migrating to v3.



## Licensed v2



Licensed v2 includes many internal changes intended to make licensed more extensible and easier to update in the future.  While not too much has changed externally, v2 is incompatible with configuration files and cached records from previous versions.  Fortunately, migrating is easy using the `licensed migrate` command.



See [CHANGELOG.md](./CHANGELOG.md) for more details on what's changed.

See the [v2 migration documentation](./docs/migrations/v2.md) for more info on migrating to v2, or run `licensed help migrate`.



## Installation



### Dependencies



Licensed uses the `libgit2` bindings for Ruby provided by `rugged`. `rugged` requires `cmake` and `pkg-config` which you may need to install before you can install Licensed.



```bash

# Ubuntu

sudo apt-get install cmake pkg-config



# macOS

brew install cmake pkg-config

```



### With Gemfile



Add this line to your application's Gemfile:



```ruby

gem 'licensed', :group => 'development'

```



And then execute:



```bash

$> bundle

```



### With Homebrew (on macOS)



```bash

brew install licensed

```



## Usage



See [getting started](./docs/getting_started.md) for guidance using Licensed as part of your developer workflow.



### Available commands



See the [commands documentation](./docs/commands) for documentation on available commands, or run `licensed -h` to see all of the current available commands.



### Configuration options



A configuration file is required for most commands.  See the [configuration file documentation](./docs/configuration.md) for more details on the configuration format and available configuration options.



### Available dependency sources



Licensed can enumerate dependency for many languages, package managers, and frameworks.  See the [sources documentation](./docs/sources) for the list of currently available sources.  Sources can be explicitly enabled and disabled as a [configuration option](./docs/configuration/dependency_source_enumerators.md).



## Development



To get started after checking out the repo, run



1. `script/bootstrap` to install dependencies

2. `script/setup` to setup test fixtures.

  - `script/setup -f` will force a clean test fixture environment

3. `script/cibuild` to run the tests



You can also run `script/console` for an interactive prompt that will allow you to experiment.



To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).



### Adding a new source



See the [documentation on adding new sources](./docs/adding_a_new_source.md) for detailed information on what's required to add a new dependency source enumerator.



## Contributing



Bug reports and pull requests are welcome on GitHub at https://github.com/github/licensed. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [Contributor Covenant](http://contributor-covenant.org/) code of conduct.  See [CONTRIBUTING](CONTRIBUTING.md) for more details.



## Disclaimer



Licensed is **not** a complete open source license compliance solution. Like any bug, licensing issues are far cheaper to fix if found early. Licensed is intended to provide automation around documenting the licenses of dependencies and whether they  are configured to be allowed by a user of licensed, in other words, to surface the most obvious licensing issues early.



Licensed is not a substitute for human review of each dependency for licensing or any other issues. It is not the goal of Licensed or GitHub, Inc. to provide legal advice about licensing or any other issues. If you have any questions regarding licensing compliance for your code or any other legal issues relating to it, it’s up to you to do further research or consult with a professional.
